My 2001 Hyundai Santa Fe's brakes have been acting strange. Occasionally, say once or twice per week (I drive at least twice per day) my brake pedal's normal resistance is replaced by a stuttering feeling. If I step off the pedal and step down again the pedal feels and works as it should. Had it checked out a couple of weeks ago at the Hyundai dealership and they couldn't find anything wrong. I did get the ball joints replaced but that didn't solve the problem.. not that anyone thought it would. Any ideas?
Could possibly be vacuum assist check valve is defective and you are feeling the engine vacuum pulsations. Easy ck, Inexpensive, easy replace. Good luck. If you will, let me know. please
Engine manifold vacuum is highest at low speeds and pedal pressure by driver is usually very light. good luck

Does it seam like you only feel it at higher speed like braking for off ramps on the interstate? Does the steering wheel shake too when the pedal is pulsating.

Thanks both of you. I will be getting it checked out this week.
Actually, it occurs when I'm going quite slowly. For example, at a place where I'm turning the corner, one where I don't have to come to a full stop.
Nope, steering wheel seems normal during these instances.
I don't actually know if it has rear drum brakes. It seems to happen more often after a rainfall, and also early on in a drive. Someone thought it could be that the brakes are getting wet and need time to warm up and dry in order to avoid any slippage. It doesn't seem to happen once the car has been running a while.
I have the stuttering brake pedal problem also. Mine will do it until the abs/ tcs light comes on. I think it is a sensor that has gone bad. This is the worst vehicle I have ever owned!
